Given numbers are 390, 726, 619, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 726) = 47190
GCD(390, 726) = ( 390 x 726 ) / 47190
= 390 / 726
= 390
Step2:
LCM(6, 619) = 3714
GCD(6, 619) = ( 6 x 619 ) / 3714
= 6 / 619
= 6
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 390, 726, 619, 457 is 1
